AGV not returning to parking point when no tasks

Hi, I am building a model on AGV in container terminals. I am having issues with making sure my AGV is returning to the parking points when the queue (Berth_Arrival 1&2) is empty. Right now the AGVs are going in continuous revolutions after there is no pick up tasks. Help me solve this problem thank you!!!

The containers in the floor storages are pushed to the AGV work list once the dwell time is reached. But since there are not work connections going to the respective CPs they are never picked up. Since there are more "active items" in the system than AGVs, the process flow keeps them driving in the look-for-work loop.

If you want the containers in the storages to be picked up you might want to use work forwarding, so they can be "seen" from other CPs ("look for work" connections).
